S-95647A203 0.094" ID x 0.25" OD Plastic Washers

Key Features & Benefits at a Glance

• Excellent chemical resistance from Delrin® Acetal Plastic material, protecting assemblies from corrosive environments and extending service life
• Maintains dimensional stability across a wide temperature range (-40°F to 180°F), ensuring reliable performance in fluctuating thermal conditions
• High Durometer 83D hardness provides superior load distribution and resistance to deformation under pressure
• Precision 0.094" ID and 0.25" OD dimensions ensure perfect fit for No. 1 screws, preventing loosening and misalignment
• RoHS 3 and REACH compliance guarantees environmental safety and meets strict international regulatory standards
• Lightweight and non-conductive properties reduce overall weight and eliminate electrical risks in sensitive applications
• Low moisture absorption maintains tight tolerances and prevents swelling in humid operating conditions

Professional Applications & Engineering Value

This Delrin® Acetal Plastic flat washer is engineered to solve critical challenges in industrial settings where metal fasteners fail. Its chemical-resistant properties make it ideal for chemical processing, food equipment, and marine applications, preventing degradation from acids, alkalis, and solvents. The material's inherent low friction and high stiffness reduce wear on mating surfaces and maintain clamp force in assemblies using No. 1 screw sizes. With consistent performance from -40°F to 180°F, it ensures reliability in HVAC, automotive, and outdoor electronics where thermal cycling causes metal washers to corrode or lose tension. The white color and plastic composition also support cleanroom and medical device requirements where non-contamination and electrical insulation are paramount.

Specification Summary & Compliance

This flat washer meets precise dimensional standards with 0.094" inner diameter and 0.25" outer diameter, manufactured to consistent thickness between 0.012-0.018" for uniform load distribution. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. The Durometer 83D hardness provides mechanical durability, while the inch system measurements guarantee compatibility with standard No. 1 screw fasteners in North American industrial applications.
